如何在JSON字符串化中使用特殊字符？

Question

I am trying to stringify my json code for sending it to MVC controller. But it does not work when data contains some special characters like greater than > or less than sign <.

Here is Sample code

 function demo()
 {
     debugger
     var demo = [];
     demo.one = 'one';
     demo.two = '<just>'
     var treeBinding = JSON.stringify(demo);
     $.ajax({
         url: '/flow/demo',
         type: "GET",
         data: { dd: treeBinding },
         success: function (res) {

         },
         error: function (error) {
             alert(error)
         }
     });
 }

JSON.stringify returns a blank array in this case. Can anyone help me to get it worked?

Answer 1

First of all your declaration with array is incorrect.That is supposed to be an object but whatever case you need to check difference between object and array.However I assume that demo is an object with two key/properties which will be sent to server.

So declaration should look like this-

     var demo = {};
     demo.one = 'one';
     demo.two = '<just>';

Then you should use to escape -

var treeBinding = encodeURIComponent(JSON.stringify(demo));

You can try something like this:

 function arrayToObjectString(arr) { var returnSrt = "{"; for (var key in arr) { returnSrt += "\\"" + key + "\\" : \\"" + arr[key] + "\\""; returnSrt += "," } returnSrt = returnSrt.substring(0, returnSrt.length - 1) + "}"; return returnSrt; } function main() { var demo = []; demo.one = 'one'; demo.two = '<just>' console.log(JSON.stringify(demo)) var resultStr = arrayToObjectString(demo); console.log(resultStr) console.log(JSON.parse(resultStr)); } main();
